Design Of Land Consolidation And Rehabilitation Information System At County Level Based On COMGIS

The geographic information system to be born since 1960 has experienced more than 40 years history, along with the development of GIS, to the GIS various aspects, various levels understanding also further deepening. At present the geographic information system has used widely in the resource management, the traffic control, the environmental protection, the disaster monitors, the facility management and the urban planning and so on . Also it has the application in the land aspect,that effectively enhanced the land management efficiency and the scientificaalness and obtained the good economic benefit and the social benefit, but at present Land consolidation and rehabilitation was important constituent of the land aspect, the geographic information system also is at the exploration stage in this application. In order to promote the land consolidation and rehabilitation informatization and the scientific, this article launches the discussion in light of this:The first chapter introduction proposed research institute matter of concern, elaborated the research technique and the research significance;The second chapter first introduced the GIS conception, then elaborated the GIS present situation in domestic and foreign research and the land consolidation and rehabilitation domestic and foreign progress condition which based on the GIS conception , finally presented the domestic and foreign land consolidation and rehabilitation information system construction condition;The third chapter has carried on the system demand analysis designed on first step of system;The fourth chapter based on system demand, has carried on the system design and separately carried on the elaboration from the system design goal, the system design method, the system design principle, the system basic composition, the system realizating form, the system operating entenvironment, the system structure and the functional design; The fifth chapter has enlarged the system function realization,the system function mainly included five big modules: Graphic editor module,project administration module, potential graduation and economic benefit module, project correlation achievement management, network issue module. The system uses MO, carries on the programming with C#,then elaborated its main design thought, the main function and the main function code realization, taking five big modules as the foundation;The sixth chapter has amplified the application of mathematical model principle in the potential graduation and the economic benifit module, which laid the foundation for the potential graduation and the economic benifit analysis;The seventh chapter on the basion of system design goal, carries on the database design. It was divided into the spatial database, the attribute database, the documents database, the picture database, the video database, then separately introduced them in detail;The eighth chapter finally after the system analysis summarized the system research achievement and the innovation, also explained what this system have to be perfect .
